NAME

gethostid, sethostid - get/set unique identifier of current host

SYNOPSIS

#include <unistd.h>longgethostid(void);
intsethostid(long hostid);

DESCRIPTION

The sethostid() function establishes a 32-bit identifier for the current
processor that is intended to be unique among all UNIX systems in ex-
istence. This is normally a DARPA Internet address for the local machine.
This call is allowed only to the superuser and is normally performed at
boot-time.
gethostid() returns the 32-bit identifier for the current processor.
This function has been deprecated. The hostid should be set or retrieved
by use of sysctl(3).
